NS-500 Problem DLC2 shows OUS. No display on console

[Hassan Babar]

Hi,

We are facing problem in NS500 it was working fine since 2 years. Suddenly the console started going blank. When we press enter button on console only white light shows on display but no other response.

On web console it shows dlc2 out of service.

When we initialize NS500 we can get console display and the status of all card is green but than CO lines does not have any dial tone. We can make calls and receive calls on CO lines but cannot hear from either side.

Can anyone help?
So far, we have completely taken apart Ns500 for card servicing, upgraded version 9, removed all extension but still no change.

We have 6+32 setup. One extra card is installed for extensions. All extensions are analog.

Have you tested with another consol?
Do the analog sets remain working fine when that happens?
What does the error log say?

How about just moving to Gtandstream UCM6308 (Has 8 CO Lines) since Panasonic is end-of-life. Support will be limited.
You can have a UCM6308 + a 32 port FXS VoIP Adapter and replace the console with GRP2636.
